SPRING AIR-GUN.

' ASPl(`JII:"ICA1IOIL`-T forming part of Illetters Patent No. 302,283, dated July 22, 1884. n

Application filed March 31, 1834.

To @ZZ whom zit may con/cern:

Be it known that I, HENRY M. QUACKEN- BUSH, of Herkimer, in the county of Herkimer, in theState of N ew York, have invented new and useful Improvements in Spring Air- Guns, of which the following, taken in con` nection with the accompanying drawings, is a full, clear, and exact description.

-This inventionv consists in improved means for obtaining the requisite air-pressure for propelling from the barrel of a gun the projectile or missile, all as hereinafter more fully described, and speciically set forth in the claims.

rPhe invention is fully illustrated in the annexed drawings, wherein Figure l is a side View of my improved spring air-gun. Fig. 2 is a top plan view of the same. Fig. 3 is a longitudinal section of the same. Fig. 4 is a t transverse section on the line r x in Fig. l,

and Fig. 5 is a perspective view of the rear end ofthe air-compressing cylinder.

Similar letters of reference indicate corresponding parts. ,4

A represents the stock of the gun, and B the barrel secured thereto by a bolt, D, as shown in Figs. l and 3 of the drawings.

C represents acylindcr adapted to slide over the rear end of the barrel and fitted air-tight thereto, the rear end of the cylinder being closed and provided on its inner face witha cushion, a, of leather or other suitable material, to receive the concussion incident to the collision ofthe same with the end of the barrel, as hereinafter explained.

To the rear end of the cylinder I connect a handle, b, which is formed in one piece, with two hooks, c c.

The forward end of the stock A is provided with two or more notches,l n, on the side 'adjacent to the barrel, and in one of said notches is detachably secured a duplex hook, h, which passes under the barrel and rises on opposite sides thereof. On the hooks h and c, at opposite sides of the barrel, are att-ached elastic bands a, which serve as springs for impelling the cylinder C.

In loading the gun,the cylinder is withdrawn from the end of the barrel and the missile introduced in the bore, which is extended through the rear end of the barrel. When'the cylinder is withdrawn, as aforesaid, the forward (No model.)

terposed between the shoulder o" and latch Z,

normally carries the latch into engagement with the cylinder, as aforesaid, and the shoulderm of the trigger t engages the end of the latch Z and retains the same into its aforesaid engagement. By pulling on the trigger the latch Z becomes released from the shoulder r, and thus allows the cylinder to be impelled toward the end of the barrel by means of the springs or elastic bands a a. In the approach of the cylinder toward the barrel the air contained in the cylinderis compressed and caused to exert its force on the missile introduced in the barrel, and thereby projects the same from the barrel. adjusted by shifting the hooks 71, from one notch a to another notch, so as to produce greater or less tension on the elastic bands.

It will thus be observed that by my improvement I obtain a most efficient, simple, and comparatively inexpensive spring air-gun.

1. Ina spring air-gun, the combination of a stationary piston and movable cylinder for compressing the air, and a spring or springs for impelling the cylinder, substantially as set forth.

2. In aspring air-gun,the combination, with the barrel having its bore extended through the rear end thereof, of a cylinder sliding telescopically on said portion of the barrel, and having its rear end closed, a spring or springs drawing the cylinder toward the barrel, and alatch holding the cylinder retracted from the barrel, substantially as set forth and shown.

8. In combination with the barrel and aircompressing cylinder sliding over the end of the barrel, elastic bands connected to the aforesaid parts for impelling the cylinder, substantially as described and s'hown.

4. In combination with the barrel B,slid ing cylinder C, elastic bands c, and hooks h, the stock A, provided with two or more notches, n, for the attachment of said hooks, substantially as described and shown.

The force of the cylinder can be IOO tween thc shoulder 1" and latch l, substantially as shown and described.

7. In combination with the barrel B, aspringactuated cylinder, C, sliding telescopioally on the end of the barrel, and the cushion u. applied to the inner face of the cylinder-head, sub- 15 stantially as and for the purposes set forth.

In testimony whereof I have hereunto signed nly naine and affixed my seal, in the presence o f two attesting` witnesses, at Syracuse, in the county of Onondaga, inthe State of New York, 2o

this 15th day of March, 1884.
